The footage is of Heini Winter, a world class sled dog racer from Germany, out exercising his 16 dogs. As impressive as this is, it is not too uncommon among professional mushers. Still, it’s one of my favorite videos to watch.

I do want to note the long thin pole that Heini is holding, and using to direct the dogs. For anyone that has seen my work socializing large groups of dogs, you will know that I use a very similar long flexible sick. Having the ability to extend your reach is invaluable when managing a large group.
